Alien civilizations may have explored the galaxy and visited Earth already, a new study says

The Milky Way could be teeming with extraterrestrial civilizations that have spread across the stars, a new study found. The study offers new perspectives on the Fermi paradox, which asks why we haven't found signs of intelligent extraterrestrials in our galaxy. There are plenty of scenarios in which aliens could exist but we haven't heard from them, the study's authors wrote. Aliens may have even visited Earth, they say — just not recently enough for us to have noticed. The study suggests that aliens might wait for stars to move closer to one another before spreading across the galaxy.

The Milky Way could be teeming with interstellar alien civilizations — we just don't know about it because they haven't paid us a visit in 10 million years.

A study published last month in The Astronomical Journal posits that intelligent extraterrestrial life could be taking its time to explore the galaxy, harnessing star systems' movement to make star-hopping easier.

The work is a new response to a question known as the Fermi paradox, which asks why we haven't detected signs of extraterrestrial intelligence.

The paradox was first posed by the physicist Enrico Fermi, who famously asked, "Where is everybody?" Gaia mapping the stars of the Milky Way

Fermi was questioning the feasibility of travel between stars, but since then his query has come to represent doubts about the very existence of extraterrestrials.

The astrophysicist Michael Hart explored the question formally when he argued in a 1975 paper that there had been plenty of time for intelligent life to colonize the Milky Way in the 13.6 billion years since the galaxy formed, yet we'd heard nothing from them. Hart concluded that there must be no other advanced civilizations in our galaxy.

“Business Insider” has become a complete tabloid.

Perhaps they are waiting for humans to get a little more abundant. And for our meat to get a little more marbled.

AND conversely, a new study says Alien civilizations may NOT have explored the galaxy and visited Earth already.

It is the same thing.

This is fun and all, but just to be clear, a LOT of things MAY have happened.

OOP artifacts are fun to read up on from time to time. :)

It would be fun for them to come and show us how to govern. They could show us a Constitution almost identical to America’s and say that is how they have succeeded over the multi millenia. Watch the lib heads explode in disbelief.

Ah, I don’t know if you’ve looked around lately, but I would say a large portion of society is already heavily marbled.
